Fire stopping in Terregles

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle fire stopping in Terregles

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and cable penetrations, and the usual reasons a site gets in touch are seals disturbed by maintenance and left open and unsealed openings around new pipes and cables. Facilities teams, main contractors and managing agents in Terregles tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Hotels and care homes around smaller places like Terregles often have services added during refurbishment. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Your questions answered

Could you schedule work at a campus like Crichton University Campus for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you seal penetrations in a hotel in Terregles after a refit?

Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.

How long does a typical visit take?

It depends on the scope, but the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you work in Terregles?

Yes. Sites across Terregles are covered.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Where we can, we combine work around Terregles with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand

Advice

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Ask the designer to confirm details early on refits
  • Treat an open penetration as a priority repair
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Arrange inspection before areas are covered up

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.

Quoting for work in Terregles

What shapes the price:

  • Removal of failed or old sealant
  • Travel to remote or island sites
  • Quantities, in metres or numbers
  • Whether the work must be split into stages

Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • The postcode of the building
  • Clear photos of the problem areas
  • How the joints are reached, and at what height
  • Your programme or deadline

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or email a schedule or drawings.

Leave it or put it right?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Resealing early avoids that.

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Penetration seals near Terregles

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, with products tested for that end use. We install fire-rated sealant to that tested detail where it is specified. A 2-mile radius around Terregles takes in a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Offices at parks like Irongray Business Park (to the north-east of Terregles) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Hotels like Woodland House Hotel, 1.4 miles north-east of Terregles, are refurbished in phases, and each phase can open up compartment walls. Tenant changes at centres like Cuckoo Bridge Retail Park (to the east of Terregles) often mean new services through walls between units.

What the job involves on each surface

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.
